These Nokya Heavy Duty Headlight High Beam H7 Wire Harnesses have been designed to be plugged into your Kia Spectra's stock wiring. Aftermarket bulbs or not, your Kia Spectra stock lighting H7 harnesses are not designed to handle extended periods of use, or operation in adverse or severe conditions. To address this, Nokya offers these H7 Heavy Duty Headlight High Beam harnesses as a cheap and relatively easy upgrade to your stock Kia Spectra electrical system. They work as replacements for damaged stock H7 harness plugs, or as complete upgrades as a precautionary measure against harness plug burnouts (which can permanently damage your Kia Spectra headlight housings). These Kia Spectra Heavy Duty Headlight High Beam H7 Wire Harnesses also help to handle the increased demands of aftermarket Headlight High Beam bulbs, Nokya brand or otherwise. Each set consists of 2 harnesses.
